Geological Summary

The Raton-Clayton volcanic field is a large Miocene-Quaternary field stretching from near Trinidad, Colorado to Clayton, New Mexico. The main pulse of volcanism took place between 4 and 1.8 million years ago. The relatively youthful-looking Capulin Mountain cinder cone was considered to have been active during the Holocene, based on stratigraphic correlations of its lava flow with distant alluvial sequences. However, later work indicated the lava flow was more than 22,000 years old. More-recent cosmogenic helium dating gave an age of 59,100 years for the lava flow (Sayre et al., 1995), who site additional geomorphological evidence for a Pleistocene age for Capulin Mountain. Several other cones and vents nearby, such as Baby Capulin, Twin Mountain, and the Purvine Mesa vents, are younger than Capulin Mountain (Dungan et al. 1989). Although they were erupted during the same geomorphologic period as Capulin Mountain, their precise age is not known.
